FILE - In this Sept. 25, 2019, file photo, Senate Judiciary Committee Chairman Lindsey Graham, R-S.C., takes questions from reporters at the Capitol in Washington. Congressional Republicans have spent most of the past two years studiously avoiding any public fights with President Donald Trump, either out of party loyalty or fear of being on the wrong end of a presidential tweetstorm. That public show of unity ended emphatically when Trump announced he would be withdrawing U.S. forces from northern Syria in advance of an impending Turkish military operation against Syrian Kurdish militia fighters. Graham, Mitch McConnell of Kentucky and Ted Cruz of Texas all joined Democratic colleagues in publicly criticizing the idea, with Graham even going on Fox News to label the decision “short-sighted and irresponsible.” (AP Photo/J.
